0402WGF698JTCE厚膜贴片电阻产品概述

一、核心身份与型号解析

0402WGF698JTCE是UNI-ROYAL(厚声) 推出的厚膜贴片电阻,型号各字符清晰对应产品核心特征:

  • 0402:英制封装尺寸标识(长0.04英寸×宽0.02英寸,公制约1.0mm×0.5mm),为小型化电路常用封装;
  • WGF:厚膜贴片电阻通用系列代号,关联工艺与性能规格;
  • 698:阻值编码(3位数规则:前两位为有效数字69,第三位为倍率10⁻¹,实际阻值=69×10⁻¹=69.8Ω);
  • JT:精度等级标识,对应±1%;
  • CE:补充参数编码,关联功率、温度系数等具体规格。

该型号明确了产品的封装、阻值、精度及工艺类型,是电路设计选型的核心依据。

二、关键性能参数详解

1. 阻值与精度

标称阻值69.8Ω,精度±1%,满足多数通用电路对阻值一致性的要求,可避免因偏差导致的信号偏移或功率损耗异常。

2. 功率额定值

62.5mW(0.0625W),为25℃环境下的最大允许功耗。实际使用需结合环境温度降额(如155℃时功率需降至约30%),确保长期可靠性。

3. 工作电压上限

50V(直流/交流),超过该值可能引发绝缘击穿或阻值漂移,需与电路工作电压匹配。

4. 温度系数(TCR)

±100ppm/℃,表示温度每变化1℃,阻值变化±0.01%。以25℃→155℃(温差130℃)为例,阻值最大变化约1.3%,适配对温度稳定性要求不极端的场景。

5. 工作温度范围

-55℃~+155℃,覆盖工业级、部分汽车级及消费电子的极端环境(如低温存储、设备内部散热)。

三、封装与工艺技术特点

1. 0402封装优势

  • 尺寸紧凑:仅1.0mm×0.5mm,显著提升电路密度,适配蓝牙耳机、智能手环等小型便携设备;
  • 自动化兼容:适配SMT(表面贴装)生产线,支持高速贴装与回流焊,降低生产复杂度。

2. 厚膜工艺特性

通过陶瓷基板印刷厚膜电阻浆料+烧结制成,兼具:

  • 成本优势:比薄膜电阻更经济,适合批量应用;
  • 稳定性:抗过载能力优于部分薄膜电阻,长期使用阻值漂移可控。

四、典型应用场景

该电阻因小尺寸、低功耗、宽温范围,适用于以下场景:

  1. 小型消费电子:蓝牙耳机、智能手表的信号调理(滤波、分压);
  2. 工业控制:传感器接口电路(温度/压力传感器放大前端);
  3. 通信设备:蓝牙/Wi-Fi模块的射频阻抗匹配;
  4. 医疗电子:血糖仪、血压计的信号处理单元;
  5. 汽车辅助电路:仪表盘背光控制、传感器辅助电路(需结合整车级认证,基础参数适配)。

五、可靠性与环保合规

  • 耐温抗振:贴片封装与PCB紧密结合,抗振动冲击能力优于直插电阻,适配移动/工业振动环境;
  • 环保标准:符合RoHS 2.0、REACH要求,无铅无镉,适配全球市场;
  • 一致性:批量生产阻值/精度一致性好,降低电路调试难度。

六、品牌与品质保障

UNI-ROYAL(厚声)是国内电阻行业领先品牌,拥有多年厚膜电阻研发经验。0402WGF698JTCE经阻值分选、功率老化、温度循环等严格测试,每批次产品符合规格要求,为制造商提供稳定供应链支持。

该产品以高性价比、宽温适应性,成为通用小型电路的优选厚膜贴片电阻。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
